Several facts contradicted this assumption: (1) Glutamate is a non-essential AA, but it is the most abundant AA in brain, (2) Large doses of Glu within the brain extracellular fluid (physiological range is 0.52 mM) induce overexcitation in neurons and thus, this AA is neurotoxic, so its concentration must be tightly controlled, (3) Glu does not enter the brain in appreciable amounts, except in the circumventricular organs and finally, (4) Glu is synthetized in the brain in large quantities
